background: determination of the impact of angiogenesis on tumor development and progression is essential. this study aimed to determine the serum levels of vascular endothelial growth factor (vegf) and interleukin 6 (il-6) in breast carcinoma, and to correlate them with tumor size, lymph node involvement, and cancer stage. methods: under aseptic precautions 5 ml of venous blood was collected f...

normal 0 false false false en-us x-none ar-sa background: exposure to some environmental agent such as different nutrition and contact with allergens may have a role in developing multiple sclerosis (ms). the present study was aimed to evaluate the cow’s milk allergy (cma) in ms patients compared to healthy controls. materials and methods: between march 2012 and july 2012, 48 ms patients were s...

in this study, aluminosilicate mcm-41 has been found to be an efficient catalyst for reaction betweendifferent benzaldehyde derivatives and 5,5-dimethyl-1,3-cyclohexanedione to give open chain analogue of1,8-dioxo-octahydroxanthene in excellent yields. no evidence for the formation of cyclization products wasobserved. the catalyst can be used several times after recovery.

the aim of the present research was to study the effect of different concentrations of rosemary (rosmarinus officinalis l.) extract, (0, 10, 12.5, 16.6, 25 and 50) mg/l added to semen extender, on sperm qualitative and quantitative parameters after freezing-thawing process of rooster sperm. 10 ross strain rooster were used. semen samples were collected, 2 times a week. after adding the samples ...

up-regulation of cd4+cd25+cd127low/- regulatory t cells (tregs) is a new target in the treatment of asthma. human bone marrow mesenchymal stem cells can up-regulate cd4+cd25+cd127low/- regulatory t cells in vitro,  meanwhile, heme oxygenase-1 (ho-1) plays an important role in the development and maintenance of cd4+cd25+ regulatory t cells. however the mechanism has not yet been adequately under...

in this paper, the adsorption of cerium on modified mesoporous aluminosilicate (with si/al mole ratio of 10) was studied. the effects of ph, contact time, initial concentration of cerium on adsorption of cerium were investigated. the adsorption capacity was high in the ph range of 4-8 and decreases with decreasing of the ph value. the langmuir and freundlich isotherms were applied to represent ...

normal 0 false false false en-us x-none ar-sa background: in some studies, the level of adenosine deaminase ( ada) in sputum and effusion liquids was used for the diagnosis of tuberculosis (tb). but it is not always possible to access these materials. the goal of this study is to assess the diagnostic value of serum ada levels in pulmonary tb patients. materials and methods: in this study, 40 s...
